ROTATION

ROTATION is used in VLBA test observations to specify an increment to the subreflector rotation value used for the subreflector position. This is added to the nominal position known by the on-line system for the particular receiver.

Note that changing the rotation also changes the pointing offset in a frequency dependent manner.

• Argument: A rotation angle in degrees.
• Options: Any rotation angle
• Default: 0.0
• Usage: Default to previous scan.
• Example: ROTATION = 10
